Street Avenger 570 Help

I'll bet the smaller jets in the street avenger might have something to do with the regular 600 not having a secondary metering block from the factory.

I don't know about smaller than similarly wet flowed carbs or not, but I went 11.91 @ 112, 1.60 60' with my 670 street avenger a couple weeks ago, with 4* less initial than I usually run, full tank of gas, and my trailer's spare tire in the trunk. Was trying to run 12.00- oops.

I'd be real interested to see what my car would do with a 770.

Full disclosure, my carb is jetted up two sizes from factory and has jet extensions. Otherwise is as it came from Holley.
